A new and flexible carburetor diaphragm is absolutely crucial for your vacuum-operated carburetor to function optimally. This diaphragm is specifically manufactured to fit several models within the Zenith/Stromberg CD series, as well as Pierburg CDUS and CDT.

A dry, stiff, or cracked diaphragm prevents the carburetor's vacuum piston from lifting correctly. Symptoms of this often include the engine losing power during acceleration, running roughly, misfiring, or consuming an excessive amount of fuel. Replacing a bad diaphragm is a relatively simple yet highly effective measure to restore your engine's original performance and smooth throttle response.

Compatible Carburetor Models / Applications:
